## AQA Computer Science GCSE

**July 2019:**the AQA CompSci area is almost complete. Most of the content for units 3-6 is now up and there's quite a lot of Unit 7 material. There's still some work to do, particularly on Paper 1 units, but it's getting there.

### Programming Concepts - Mathematical Operators

Basic mathematical operators are addition (+), subtraction (-), multiplication (*) and division (/). BIDMAS rules apply when you're using these, so take care, especially when dealing with multiplication and division.

Basic Mathematical Operators - notes from class

Some exam style questions dealing with operators and trace tables. It would be a good idea to code these questions in Python as well.

Question 0 - a simple introduction

Question 2 - a bit trickier (particularly the last part)
